A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get
28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes, find the empirical probability of getting color P(R).
O A. 6/25
OB. 1/4
O C. 3/10
O D. 13/50
Answers
Answer:
B
Step-by-step explanation:
28+25+29+18 = 100
red = 25
25/100 = 1/4
The required empirical probability is 1/4 which gets the color of red P(R).
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get
28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes
To find the empirical probability of getting a red outcome, we need to divide the number of red outcomes by the total number of spins:
P(R) = 25 red outcomes / 100 spins
Apply the division operation, and we get
P(R) = 1/4
Hence, the required empirical probability is 1/4
Therefore, the correct answer is 1/4 or option B.

what is the squareroot of 144
Answers
Answer:
The square root of 144 is 12
Step-by-step explanation:
[tex]\sqrt{144} = 12[/tex]
because 12 x 12 = 144
it's basically 12 doubled... [tex]12^{2}[/tex]
Answer:
12 is the square root of 144.
Step-by-step explanation:
That means if you multiply 12 by 12, you will get 144.
That's called 12² (12 squared)
The square root is the opposite of that. √144=12.
Keep in mind that 12*12=144.

Step-by-step explanation:
Define all the exemptions that applie:
exemption for being married: $3000
exemption for 1 dependent: $ 1,500
3000 + 1500 = 4500
Subtract the exemptions from the yearly earnings:
67000 - 4500 = 62,500
Now, applied the 3.5 % tax
3.5 / 100 = (0.035)

What is the area of a rectangle with a length of 5 units and a width of 8 units
Answers
Answer:
40 square units
Step-by-step explanation:
A = LW
A = 5 units x 8 units
A = 40 square units
Answer:
40^2
Step-by-step explanation:
The formula for finding the area of a triangle is length times width. So all you have to do is multiply the length 5 and width 8 together to give you 40. Therefore, the area of the rectangle is 40^2.
Note that a change can be an increase or a decrease.
For an increase, use a positive number.
For a decrease, use a negative number.

Is 8 a solution to the equation x+6=x+6
Answers
Answer:
If you mean could x be eight, then yes, x could equal eight. However, any number could be the solution as this equation has an infinite solution.
Step-by-step explanation:
Once again, I am going off of you are asking if eight could be x. If that is what you are asking, here is the reason.
The equal sign shows that both sides equal each other. If you plug in 8 for x, then you get:
8+6=8+6
14=14
Does 14=14? Yes, so plugging in eight for x works. However, looking at this, we can see that your solution would actually be an infinite solution. This is because, no matter what number we plug in for x, we will get a true statement.

Suppose that the members of a student governance committee will be selected from the 40 members of the student senate. There are 18 sophomores, 12 juniors and 10 seniors who are members of the student senate. In how many ways can the governance committee be selected, if it must be made up of 2 sophomores, 2 juniors and 3 seniors? Assume that each of the sophomores, each of the juniors and each of the seniors is equally likely to be selected for the committee.

Using the combination formula, it is found that the committee can be selected in 1,211,760 ways.

A principal of $350x is invested at 8 % interest for 5 years. Determine the future value
if the interest is compounded quarterly .
Answers
After being compounded for a period of 5 years, the amount will rise to $5,200.82.
The interest is given on an annual basis and so is the period yet the compounding period is quarterly. The first thing to do therefore, is to convert the interest and period to quarterly measures.
Interest = 8% / 4 = 2% per quarter
Periods = 5 x 4 = 20 quarters
Amount will be $3,500
The amount after 5 years will be:
= Amount x ( 1 + rate) ^ number of periods
= 3,500 x ( 1 + 2%) ²⁰
= $5,200.8158859
= $5,200.82
In conclusion, the amount will be $5,200.82 after 5 years.

Howard's stew recipe makes 6 servings and uses 2 carrots and 3 ears of corn. Drag carrots and corn into the box to show how many Howard needs for 12 servings.
Answers
Answer: 4 carrots and 6 ears of corns
Step-by-step explanation:
Howard needs 4 carrots and 6 ears of corn for 12 servings of stew.
How many carrots and ears of corn does Howard need for 12 servings of stew?To get how many carrots and ears of corn Howard needs for 12 servings of stew, we can set up a proportion based on the number of servings.
Let x be the number of carrots
Let y be the number of ears of corn needed for 12 servings.
Proportion:
6 servings of stew need 2 carrots and 3 ears of corn
12 servings of stew need x carrots and y ears of corn
(2 carrots) / (6 servings) = (x carrots) / (12 servings)
(3 ears of corn) / (6 servings) = (y ears of corn) / (12 servings)
2 * 12 = 6 * x
3 * 12 = 6 * y
24 = 6x
36 = 6y
Solve for x and y:
x = 24 / 6
x = 4
y = 36 / 6
y = 6.
